Any time there are changes to a major website or company there are going to be issues with all the changes, however, FeaturePrice does offer an online .pdf manual which makes using there control panel very easy, however, most users will not take the time to read "how to" they would much rather pick up a telephone & demand support right away. The reason for all the problems is they switched from the old Plesk servers (referred to as Legacy) so now are offering much more sophisticated features in there control panel which makes it difficult if you are not an advanced user in certain programming fields but really has an excellent pkg. on disk space & bandwidth.
I am in no way affiliated with the company, just giving my 2 cents.
